Hi, I discovered that bug today and wrote a patch, I tested it against mailman 2.1.13 (as found in Squeeze); I tracked the change in Mailman and found it to be revision 972:

This allows changing options for and unsubbing an address which contains a double-quote character. -- http://bazaar.launchpad.net/~mailman-coders/mailman/2.1/revision/972 Fred --- listadmin.pl.orig 2013-09-14 13:10:33.760699371 +0200 +++ listadmin.pl 2013-09-14 13:11:54.785101152 +0200 @@ -588,7 +588,7 @@ sub url_quote_parameter { my $param = shift; - $param =~ s/(\W)/sprintf ("%%%02x", ord ($1))/ge; + $param =~ s/(\W)/sprintf ("%%%02X", ord ($1))/ge; $param; } @@ -1763,6 +1763,7 @@ user => \@addresses); for my $a (@addresses) { $params{$a .
